Title: Plate product winding method and device
Inventor: TOUGE SHINJI
IPC: B65H54/28
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To wind a plate product with compact equipment and small power by guiding with twisting specific angel at a traverse part the plate product, continuously extruded in a horizontal state by an extrusion molding method, so as to traverse laterally in the state of its cross direction being almost upright and circumferentially rotating in the horizontal state of the plate product further twisted by a specific angle. SOLUTION: Clamp mechanism 12 is of such structure as to clamp a core cylinder 131 of a winding drum 13 with collar parts 132 provided outward from both ends of the core cylinder 131, in the state of journalling them from both sides and to make the winding drum 13 circumferentially rotatable by driving its shaft. At this time, a plate product fed from a traverse part is wound on the winding drum 13, in a horizontal state further twisted by about 90 deg.. A winding drum 13' having wound the plate product 2 being traversed can be placed on a truck 14 by detaching the clamp mechanism 12 after stopping driving of the shaft, and can be taken out backward. The plate product 2 can therefore be wound continuously in a plane state with compact equipment and small power.

Title: Photo diode
Inventor: SUSA NOBUHIKO
IPC: H01L31/10
Filed: 1982-10-22
Abstract: PURPOSE:To obtain a photo diode of a much higher response speed by a method wherein a P<+> layer, an N-layer, and an N<+> layer are continuously connected in juxtaposition in this order on an insulation substrate. CONSTITUTION:On the substrate 10 insulated by doping Fe into an InP substrate, the P<+> layer 11, the N-layer 12, and the N<+> layer 13 of InGaAs are continuously connected in juxtaposition. Electrodes 15 and 16 are provided in the utmost proximity to P-N junctions 18 and 19, and the surface is covered with an insulation reflection preventing film 17. In a depleted state of the layer 12, a light L of a larger energy than Eg of the layer 12 is made incident through the film 17. When the layer 12 is changed into a direct transition type, generated electron holes do not take a diffusion process, but only transit through the layer 12, and therefore the current response speed to the light is much higher than by a conventional photo diode. Besides, the area of the P-N junction 18 is extremely narrow, and the capacity, the electrodes 15 and 16 form via the film 17 can be also neglected. Accordingly, high speed actions can be performed by connection to an external circuit.

Title: Solenoid valve
Inventor: KISHIMOTO TERUBUMI
IPC: F16K31/06
Filed: 1981-11-20
Abstract: PURPOSE:To provide a solenoid valve which can be functioned both as a closing valve and an opening valve by forming two valve seats for closing and opening a flow path connected to one opening. CONSTITUTION:In case where an opening 15 is used for an inlet, and an opening 25 is used for an outlet, a solenoid valve functions as a constantly closing solenoid valve, and on the contrary, in case where the opening 15 is used for an outlet, and the opening 25 is used for an inlet, it functions as a constantly opening solenoid valve. When an electromagnetic coil 6 is excited, a plunger 8 is moved upward, so that a valve body 28 is brought into contact with a valve seat 9a, and a valve body 30 is separated from a valve seat 4a, which results in that the space between the opening 15 and the outlet 18 is opened, and the space between the opening 25 and the outlet 18 is closed up. The valve body 28 is pressed against the valve seat 9a by an internal spring 29 and pushed into the interior of the plunger 8 by the valve seat 9a to be kept in the state of pressure contact.

Title: Limiting circuit for gate voltage for switching circuit device
Inventor: MOURICK PAUL DR
IPC: H03K17/0812
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a limiting circuit which can achieve a short-circuit resistant property by a method in which a diode is connected in series with a gate resistor, a clamping diode is connected in parallel with the resistor in such a way that its cathode becomes the side of an emitter and a diode for draining is connected to every gate in such a way that the cathode becomes the side of a gate power supply. SOLUTION: In a limiting circuit, an intrinsic gate resistor is installed at every IGBT module, and a gate resistance Ron at a time when an IGBT is turned on is different from a gate resistance Roff at a time when the IGBT is turned off. Then, the interaction between gate terminals is prevented by a diode which is connected in series with the low-ohmic gate resistance Ron for turning-on, and a high-speed expitaxial diode whose parasitic capacitance is small is favorable as a diode at a gate circuit. In addition, in order that a gate voltage which is higher than a power- supply voltage at a drive stage is not generated due to the counteraction of the internal capacitance of the IGBT, a drain diode is installed so as to be added to the power- supply voltage at every module. As a result, the short-circuit resistant property of the limiting circuit can be achieved.

Title: Method and apparatus for protection of masquerade attack in computer network
Inventor: DEBITSUDO AREN KOORUMAN
IPC: G06F21/44
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To securely prevent access from a hacker's machine. SOLUTION: An authorization session key is generated on an authorized machine according to the CPU identification number, hardware constitution, and time stamp of the machine. An authorization machine retrieves the same information as to the authorized machine and generates a session lock which is effective in a specific time interval. When a session key to join matches one of session locks and is not in a list of used keys, the session key is added to the list of used keys and the access is allowed. Thus, a one-time use key is used. The lock and key can be generated between time stamps, so a user requests services plural times from the same machine without waiting for a prescribed time between requests, and a front end for a masquerade protection tool can write retrial until access is successful.

Title: Method for applying paint containing zinc powder
Inventor: DEGUCHI TAKENORI
IPC: B05D7/24
Filed: 1981-11-19
Abstract: PURPOSE:To enable to obtain excellent adhesiveness even when paint is applied within a short time after being prepared, in coating a cold-rolled steel sheet, by repeating the agitation of the paint where zinc powder is dispersed into a binder in company with standing periods, and then applying the paint. CONSTITUTION:After a cold-rolled steel sheet is degreased and acid-pickled, an aqueous solution for stabilizing a film on the metallic surface is applied to it so that the total amount of chromium contained in the film is controlled at 30mg/m<3>, to form an underbedding fim. Thereafter, epoxy paint containing zinc powder at a ratio of 85wt% based on a dry paint film is applied to obtain an anticorrosive steel sheet. Hence, the zinc powder-contg. paint must be matured for about 6 days until its application after preparation; otherwise the excellent adhesiveness of the paint film would not be obtained. However, when  the paint is repeatedly agitated, e.g. once a day for on hour or twice a day for  one hour every cycle in company with a standing period, to uniformly disperse  the zinc powder, the maturning period can be shortened to about 2 days.

Title: Multiplex terminal station equipment
Inventor: MATSUOKA SHINJI
IPC: H04J14/02
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To realize large capacity transmission with a single system by converting k-parallel electric signals after the constitution of a transmission line frame into k-parallel optical signals different in wavelengths with each other, multiplexing the wavelengths, transmitting them by the same optical fiber and executing a demultiplexing processing with the respective wavelengths on a reception-side. SOLUTION: A transmission line frame constitution circuit 12 constitutes a transmission line frame for the k-parallel signals in the middle of multiplex and outputs the k-parallel electric signals. The k-parallel electric signals are converted into the k- parallel optical signals different in the wavelengths with each other. An optical multiplexer 14 multiplexes the k-parallel optical signals and transmits them to an optical fiber transmission line 1. An optical demultiplexer 25 demultiplexes the signals into the k-parallel optical signals of the respective wavelengths. The k-parallel optical signals of the respective wavelengths are converted into the k-parallel electric signals. Identification reproduction circuits 23-1 to 23-k identify and reproduce the k-parallel electric signals. A transmission line frame terminating circuit 22 executes the transmission line frame terminating processing of the identified/reproduced k-parallel electric signals. Thus, the single system can be realized at processing speed being 1/k of multiplex speed.
